I have an F80 and love it. It has plenty of bells and whistles that I don't use or understand, but there are two key features it has that my Nikkormat and MF don't: AF and bracketing. I don't always use either, but they are very handy nonetheless.
AF is great, but I detest scrolling around to change my AF points, so I often rely on manual focusing still. No problem. And I like to bracket. Whether to test out a new film or to get three different exposures of a shot I really like, it's handy to have. I can try to "see" my finished product, but my brain is not beyond making mistakes. Quick and automated bracketing gives me a safeguard when it matters most.
